One of the Kardashian girls pregnant?

Khloe Kardashian posted this on her instagram page asking fans to guess which of the Kardashian girls is pregnant as a pregnancy test is flashed. She posted a photo of herself, Kim, Kris and Kendall Jenner but ruled out their mother Kris Jenner by calling 'Miss Menopause". So who is it? Kim already said she's not pregnant, Kendall is 19 and a model...possibly not her, so is it Khloe herself? She told fans to watch out for the answer in new episodes of the family reality show and later deleted the post
